Whats on the test?

1 . Mechanics
- functions and relations
- domain/range (x+y display graphs as proof)
- calculator stuff
(tracing, evaluating, windows, zooms, tables, graphs... etc.)


2. Quadratics

y-k=a(x-h)^2 form..
=(h,k) vertex
a ..determines opening..

OR..

y=ax^2 + bx + c Standard form.

- symmetric
(about the axis of symmetry)
y=ax^1 - linear
y=ax^2+bx -quadradic
y=ax^3+bx^2+cx -cubic

2 kinds of questions..
a) your given the function, answer questions
b) given table of values ; DO regression from the stat plot QUADREG

• USE ANY STRATEGY TO SHOW WORK TO RECEIVE MARKS!!

- Excel, Graphmatica, Calculator etc.

3. Cubics
*box volume or relative min./max problems

up...... minimum.

down.... maximum.

**on cubic functions, there is a RELATIVE maximum and a RELATIVE minimum.


4. Exponentials

no e questions

WILL have to use EXPREG to create y=a.b^x
